Use anonymous events to download logged data from another device. https://github.com/mbientlab/MetaWear-SDK-iOS-macOS-tvOS/blob/2.10.0/MetaWear/Classes/Core/MBLMetaWear.h#L357

What is the value returned from reading the macAddress property and what is the value on the device?

Did you setup the ble connection for high frequency streaming? https://mbientlab.com/csdocs/latest/advanced_features.html#high-frequency-streaming
-
Read the README or the documentation.

Check with the Android or iOS MetaBase apps as well. You can use those versions of MetaBase to upload any firmware revision you want. No, MetaBase code is not publicly available. Post the code you are currently running to configure the sensor…
-
All you need to do is call downloadAsync when you want your logged data. You don't need to do anything else beyond that.
-
Please provide some data that illustrates this timestamp issue you are seeing. There is no real time clock on the device. It does know how much time has elapsed and relies on the the host device to recalculate timestamps. When connection is e…

I am not sure what that error means. The message seems like it's a permission error though you would probably be better asking this on an Android specific forum.

Have you tested the previously linked commit with your apps? i would like to know if the fixes work for you before releasing it.

Do the boards properly work with the MetaBase app? https://www.microsoft.com/en-us/store/p/metabase/9nblggh4txj3

No, I don't think any further discussion is needed. The 133 status is a generic gatt error code returned from Android's BT stack that plagues every Android device, and it sounds like you already have a working solution to this issue.
-
See this thread:https://mbientlab.com/community/discussion/1934/metahub-timestamps/ Generally speaking, timestamps for streamed data shouldn't be too heavily relied upon. However, if you are running the latest firmware (v1.3.6), you can replac…

Please see my post from that thread (2nd post): https://mbientlab.com/community/discussion/comment/5705/#Comment_5705 I should rephrase "power off" to "resetting". In your tests, are all timestamps incorrect and offset by the same amount, or …
-
Are you streaming from them simultaneously?
-
This thread should address your questions:https://mbientlab.com/community/discussion/comment/5719 Anonymous routes are somewhat limited in that the board cannot lose power if the data is being retrieved by another device.
-
Yes, i know you want GSR and temp. Please link to the specific sensors so we can see if they are compatible. The answers to your questions depends on the specifications of your components. In general, yes, you should be able to connect both sens…

It will be added but it's not a high priority item. What is your use case with the boards that requires this information?
-
just a quick update, we are looking into it and will update the thread when we have more details.
-
There really isn't anything other than connecting your external sensors to the GPIO pins. You may need to add additional components depending on the sensor's electrical specifications. Which components exactly are you looking to connect?
-
Hrm, I'll have to look into this issue. Off hand, removing the route should clear the subscribers as well so it's odd that you are still receiving data on your old route. For now, you can use a boolean flag to only execute a piece of code one tim…

You will need to sign a contributor license agreement before we can accept pull requests. Email "hello at mbientlab dot com" with your GitHub username to request the agreement. That said, the documentation is internally maintained so you can just …

They are not the same thing but for the purposes of this conversation, they are interchangeable. You receive one if the task is successful, which, it sounds like it was at some point if you are getting periodic reads. However, since you never r…
-
You will probably need some customizations then if you indeed want a bigger battery or a wired solution. However, that seems like a waste of money when you can get months of use on 1 CR2450. If you still want to pursue this path, contact Mbientla…

* What is the error returned from connectAsync? * If you simply try to connect again after the first call fails, without doing a scan, does it eventually succeed? * What are the steps to reproduce this issue? * What Android devices and OSes are y…
-
Ah ok, I was looking at the MetaTracker page. Well, how long do you need the board to run on a single battery? As stated in my previous post, actual battery life depends on what features / sensors you are using and how frequently you are sampli…

Did you ever remove the previously created timers or are you continually scheduling new tasks? It sounds like you are scheduling tasks but never removing them. The ScheduledTask interface has an id method https://mbientlab.com/docs/metawear/andr…

The README on the desktop documents MetaBase's command line arguments. You can control which HCI device is used by setting the NOBLE_REPORT_ALL_HCI_EVENTS env variable. For example, to stream acc at 200Hz to hci1 (execute from the ~/Apps/MetaBase…

So, as the error message states, the ble packet doesn't have space for the accounter information when using it with quaternion data. There is an alternative mode that appends a counter instead of timestamp data but the android SDK needs to updated …

Where on the website did you see "4 weeks"? The CR2450 can last you months depending on the use case.
